Special mechanical bin cleaning device for ore bin and bin cleaning method

Abstract

The invention discloses a special mechanical bin cleaning device for an ore bin and a bin cleaning method. Two guide pulleys are mounted at the front side of the top of the ore bin, the left side and the right side of the top of the ore bin are each fixedly provided with a guide steel wire rope, a row of rake teeth are arranged at the left side and the right side of the front end of a rake frame at intervals, and the front ends of the rake teeth are gradually inclined downwards relative to the rear ends; the front ends of the harrow teeth are 2-6 cm higher than the bottom of a harrow wheel, the lower ends of the two traction steel wire ropes are fastened to the front end of the harrow frame, the upper ends of the traction steel wire ropes wind around the corresponding guide pulleys and then are fastened to the front end of a slide steel plate, a movable pulley is mounted at the rear end of the sliding steel plate, and a main steel wire rope of the winch winds around the movable pulley and then is folded back to be fixedly mounted; the left end and the right end of the sliding steel plate are each fixedly provided with a guide tube, and each guide tube is arranged on the corresponding guide steel wire rope in a penetrating and sleeving mode. The invention further discloses an ore storage bin cleaning method using the special mechanical bin cleaning device for the ore bin. The special mechanical bin cleaning device reduces labor investment, reduces production cost, improves production efficiency and reduces potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of mine construction equipment, in particular to a device specially used for mine bin cleaning. Background technique [0002] Ore generally has the characteristics of water softening, dehydration hardening, and strong cohesion. Because the ore has a large angle of repose in the mine bin, it accumulates more and more, occupying the effective volume of the mine bin and seriously affecting the normal transshipment of the ore. At present, there are two ways to clean up the bonded minerals in the mine bin, which are manual clearance and blasting clearance. However, manual clearing is very difficult, time-consuming, inefficient, and has a high risk of collapse and fall safety; blasting clearing involves management of explosive materials, and the management of personnel safety, buildings and surrounding equipment and facilities during blasting is extremely risky. There are countless safety accidents in the proces...
